Abstract: 509,757. Ventilating vehicles ; vehicle windows. DUTFIELD, A. E., RAWLINGS, E. J., and RAWLINGS MANUFACTURING CO., Ltd. Oct. 20, 1937, Nos. 28626/37, 33052/37, 2521/38, 9765/38, 26143/38, and 27778/38. [Classes 20 (iii) and 137] Ventilating means is arranged within the normal window space in the side of a vehicle and provides an air passage even when no part of the glass panel is in an opened position, baffles being provided to ensure air extraction due to the passage of air past the window when the vehicle is in motion. A ventilation gap is formed in a centre panel 2 between two side panels 3 mounted above a glass pane, and arranged in the window space. A hood or cover-plate 4 is spaced from the gap to form an air tunnel 5 at the ends of which are pivoted flaps 6 which direct the air current over the hood 4, and cause an extraction of the vitiated air. Two of such flaps 6, which may be made of rubber, may be fitted when the vehicle such as a tram car is adapted to move in either direction. In Figs. 8 and 9, the ends of the chamber 5 are closed by vertical box-like members 8 which are open at the side to the chamber 5, and laterally at the ends 8<1> for extraction of the vitiated air. The members 8 may be extended horizontally at 8<1>, as in Fig. 12, and terminate in louvres 8x. The box-like members may be open, and louvred along their external face as at 10, Fig. 17, and provided with a hollow cylindrical shutter 11 having a cut-away portion 11x, so that, by rotation of the shutter, by a handle 12, the air passage may be opened or closed. The cover plate may be formed of two relatively slidable portions 4a, 4b to allow of access to the interior through the window. The cover-plate 4c may be hinged about its upper horizontal edge and opened and closed by a rack and pinion device operated by a handle 14. In modifications, fixed glass panels 15 are separated by gaps having louvred chambers 16, the centre panel being either flush with the side panels or in a different plane, and certain of the panels may be slidable as 15c, 15d.

Filed: 1938-10-03
Abstract: 513,819. Torque measuring wrenches. AUTOMOTIVE MAINTENANCE MACHINERY CO. Oct. 3, 1938, No. 28703. Convention date, Dec. 20, 1937. [Class 106 (ii)] [Also in Group XXIII] A work-engaging member 11 and a grip member 15 are fixedly secured to opposite ends of a spring bar 10, the deflection of which is measured by means allowing unobstructed free flexing of the bar. The member 11 has an opening 13 extending at right angles to its axis in which the forward end of the bar 10 is freely received and clamped by set screws 14. An adapter element 12 is fitted to engage a socket. A flat strip 16 overlying the member 10 has its forward end mounted on an upstanding stud 17 on the member 11 and is held in place by a nut 19 and washer. The other end is offset and lies close to the grip. The extreme end is widened and extended on both sides to provide a scale reading from a central zero which registers with an index mark on the grip. Accidental displacement of the end 16a is prevented by a U-shaped guard 24 the legs of which are secured to the ends of the part 20 by screws 25. In a modification, the scale is formed on a grip shaped like a knob and a long pointer attached to the head moves over this scale. In a further modification, the end of the strip 16 carries a dial indicator, the pointer spindle of which has a pinion engaging a rack extending at right angles to the bar which is of rectangular section, the rack being adapted to slide along the bar and being kept up to the pinion by a small spring. In this form the head is provided with ratchet teeth on the lower face adapted to engage similar teeth on a part connected to the adapter, which can slide axially of the head a limited amount for the teeth to clear one another. When the device is moved clockwise the work is under torque, when moved counter clockwise the ratchet teethcarry the head away from the adapter. In a further modification, the scale member 20 registers with a mark on a plate which has a small adjustment transversely of the device by screw and slots.

Abstract: 1,020,250. Machine tool details. TOYADA MACHINE WORKS Ltd. July 15, 1964 [July 16, 1963], No. 29147/65. Heading B3C. [Also in Division F2] A means for controlling pre-load applied to a bearing by fluid pressure comprises an adjustable valve which regulates the pressure of the fluid. In an embodiment, a boring machine has a shaft 1 with a loose sleeve 2 and ball bearings 7, 7<SP>1</SP> mounted thereon; a shaft-cover 3 and a body 4. Outside faces of a pair of ball bearings 7 are pre-loaded by pressurized fluid supplied to an annular chamber 9 formed between the cover 3 and the sleeve 2, the pressurized fluid forcing a ring 8 which is slidably mounted on the sleeve 2, against one of the outside faces of the bearings 7. The axial thrust is transmitted through the inner faces of the bearings 7, through the shaft 1 having a thrust washer 17 mounted thereon, and to inner faces of the bearings 7<SP>1</SP>. The pressurized fluid is supplied to the chamber 9 from a reservoir 19 by a pump 10, and, a valve 13 regulates the supply of fluid to the chamber 9. In operation, when pre-loading is not required the valve 13 connects a supply pipe 20 back to the reservoir 19 via a return-pipe 21. When pre-loading is required the valve 13 connects the pipe 20 to the reservoir 19 via a return pipe 22 having a throttle 15 therein and pressure is effected in the chamber 9. When a greater preloading is required the valve 13 connects the pipe 20 to the reservoir 19 by a return pipe 23 via throttles 15 and 16.

[Class 38 (iv)] In an automatic arc welder the electrode is positioned to maintain the arc p.d. at a predetermined value. As shown, Fig. 1, the welding rod 2 connected across the output of welding generator 1 is positioned by the rollers 4 driven by the reversible motor 5 energized from generator 6. Auxiliary self-excited generator 10, coupled to 6, excites both 5 and 6 and applies a voltage, in opposition to that of 1 to the second field winding 9 of generator 6. The sense and magnitude of the excitation of generator 6 is thereby varied in response to changes in the output voltage of 1, i.e. the arc potential, and the motor 5 rotates to correctively position rod 2. The device may be modified to control an A.C. welding plant by rectification of the A.C. arc voltage before application to field 9.
